Specification of Letters Patent.

Patented Dee. 29 1914.

Application led October 27, 1913. Serial No. 797,573.

To all whom it may concern:

Be it known that I, Gnome WV. STANLEY, a citizen of the United States of America,- residing at Marienthal, in the county of lVichita. and State of Kansas, have invented certain new and useful :improvements in Gearing, o which the following lis a specification. Y

"ihis invention relates to a gearing and more particularly to a gearing adapt-ed for use in conjunction with Wind-mills and an ranged to serve as a pumping ack.

'Further objects and advantages of the invention will be set forth in the detailed descripticn wljiich now follows. v

fn thefaccoinpanying drawing, Figure l is a'side''elerationA of a gea'rirng constructed in accordance with the invention. Fig. 2 is av detail sectional view `illustrating the mounting of one ofthe sprocket wheels, and Fig. 3 is a detail View of a portion of one of the side bars of the superstructureffurther illustrating --the 'methodof mounting one ot' the lower sprocket wheels for vertical adj ustmentflr Y Like numerals designate corresponding parts in ax'll of the figures of the drawing.

-Referlhgto the drawing, the numeral 5 desiguatesl a tower, preferably provided with rface-way 6 in a member Gathereof, for the` geception of. balls or like anti-friction i'enibers A tubular sleeve 8 has a neck extension 9 which depends into and is guided. by the member 6. A

The-top of the towerl is provided with a nular collar 11 carried bythe super-strueture hereinafterA described. This mounting provides a turn table for supporting said srxpcnstructure which comprises side bars :.5 and a yoke 1G, said yoke being of inverted U-shapeand being riveted or otherwise secured to the side bars at 17. A transverse shaft 18 is mounted -inbearings 19 of the yoke and is held against endwise movement by collars 20. v

Any desired type of wind-wheel conventionally illustrated at 21, is mounted upon shaft 18, and it isto be understood that since the invention relates to the gearing and not to the specific type of windmill, any desired'form of Windwheel may be eniployed to drive the shaft 18. The same 1s true with relation to the type'of vane emp loyed. For the purposes of this application, I have merely conventionally illustrated a. vane 22 hinged as is'usual at 22" between ears 22", though other ways of mounting the vane 'and wind-wheel are possible.

The shaft 18 carries spur gear wheels 23 which mesh with spur gear wheels 24,1 the latter being mounted upon stub shafts-25 journaled in bearings 26 of the yoke. l pen the inner ends of these stub. shafts, sprocketv wheels 27 are mounted and these sprocket wheels receive Sprocket chains 28,'the lower portions of which pass over sprocket wheels 29 that are mounted upon stub shafts 30;v

For the pur-poses of providing vertical adjustment ofthesez lower sprocket wheels for a purpose hereinafter set forth,the 1side7 bars 15 are vertically slottedat 31 andt is through',these- Slots that the. shafts O p'aSS.. These shafts are providedwith angularol-4 lars 32 and are threaded-at 33 for the rceptravel', it is apparent that'a` vertical re'ciprocation will be imparted to the connecting rod and that the length of the stroke may be varied' by changing the length of the sprocket chains and' adustin-g the lower sprocket verticallyin the slots. In addition to providing for this adjustment of the length of the stroke, it is apparent that many combinations of the other elements of the gearing may bev had. lFor instance,V by reducing the size of the gear Wheels 23,' and increasing the size of the gear wheelsfZl, less power will be required to operate the device and reciprocation may be imparted to the connect-imT rod 37 lfor the )ur ose of pumping water or for any other purpose,

with a very light breeze. Upon the other hand, where the power is ample, the speed of the connecting rod may be increased by increasing the size of the gear wheels 23 and decreasing the size of the gear wheels 24.

By virtue of the construction herein shown and described, the rotation of the 'wind` wheel is converted into a very long stroke of the plunger or connecting rod 37. At first glance, it may apperzr that there would be no particular advantage in employing one long stroke in lieu of a number of shorter strokes, but there is a sound mechanical reason ffr the statement that the long stroke requires less power in that if it requires a three hundred pound draft to raise the connecting rod, it requires at least one hundred pounds extra to start it. Therefore, comparing a single stroke four inch wind-mill pumpof the ordinary type with this gearing, it may be pointed out that in making the equivalent of a three foot stroke, such wheel makes nine revolutions or nine strokes of four inches each. Therefore, the plunger would have to be started from a position of rest nine times, requiring nine hundred pounds starting power and three hundred pounds lifting power, or twelve hundred pounds for the three foot lift. The opening and closing of the valves nine times would cause a loss of onehalf inch on each stroke, thereby losing four and one-ha1f inches out of thirty-six inches and leaving an effective stroke of only thirty-one and oneha1f inches. In the present device, however, assumirgthat all of the gearing isfour inches in diameter, athfree foot stroke would be made' in six revolutions of the wheel,'it

being assumed. that the distance from s rocket wheels 27 to sprocket wheels 29, lis tliree feet. In this complete stroke, therefore, the valves would only have to close once and therefore only one-half inch of water would be lost, orfin other words, thirty-five and one-half inches of water would be raised, and requiring a three-hundred pound draft for the work and one-hundred pounds starting draft, or a 'total of four-hundred pounds draft for the entire three foot stroke,

thereby saving the difference between four hundred pounds and twelve hundred pounds, or eight. hundred pounds.

From the foregoing description, it will be seen that simple. and efficient means are here in provided for accom lishing the objects of the invention, but whi ethe elements shown and described are well adapted to serve the purposes for which. they are intended, it 1s -tosbe understood that the invention 1s not limited to the. precise construction set forth, but includes within its purview such changes as may be made Within the scope of the appended claims.

Having described my invention, what I claim is:

1. In a device of the character described the combination with a supporting tower of an annular bearing member which lies 1n a horizontal plane at the top of said tower, a

transverse support alixed to and supported by said tower at a considerable distance'below the top thereof, said transverse support having a central opening formed therethrough, a rotative superstructure comprisn ing a pair of opposed vertically arrangid side members, a yoke of inverted U-shape connecting the upper ends'of said side members, and a tubular sleeve comprising a cuplike upper portion and a lower neck exten-.

sion of lesser diameter than the upper portion and which extends throughthe opening in the transverse support, anti-friction devices disposed between said support and the underside of the upper portion'of vthe tuffi,"I bular sleeve, sprocket wheels journaled upon* n v the inner faces of the side members near the lower end thereof,

additional sprocket wheels journaled upon and 'near the upper portion vof the superstructure, a connecting rod operating through said t-ubular sleeve,$v`
